The phrase "amount of drag" is correct and usable in written English.
It can be used in contexts related to physics, aerodynamics, or any situation where resistance or friction is being discussed.
Example: "The amount of drag experienced by the aircraft increased significantly as it approached higher speeds."
Alternatives: "level of drag" or "degree of drag".
Even for the existing birds, they found that the amount of drag added by submerging the jaw increased the power requirement by about 20percentt.
The low-pressure area reduces wind resistance and hence the amount of drag, which means less energy is needed to maintain the same speed as the leader.
In other words, engineers want the smallest possible air intake scoops on a car to encourage the least amount of drag that such scoops cause, which slows down the car.
The flow then ceases to be laminar and the amount of drag increases sharply.In this section Sonic boon The turbulent world of swimming In your face Birds of a feather mate together ReprintsThis is particularly prone to happen when the flow rises over a bump and then descends on the other side.
An efficient design can reduce the amount of drag and thus reduce the fuel consumption of the aircraft.
When the plane accelerates through the sound barrier it becomes "choked" with air, causing an incredible amount of drag - much larger than a traditional Concorde-like design.
The amount of dragged air and air supplied from the tunnel outlet was then calculated knowing the velocity distribution and the area of the air flow.
The wobble frequencies measured by the Rossi satellite are broadly consistent with the amount of dragging expected from the neutron stars' spin rates and the distance at which the material is whirling around them.
But when other teams have investigated that concept, they see the downforce it produces, but also the huge amounts of drag, so they have not adopted it.
With the large amounts of drag performers being targeted over the last few weeks, many are seeing this as form of discrimination.
Even if the Bush tax cuts are extended and the sequester delayed, a huge amount of fiscal drag remains in place.
